HOT-COKE CONVEYER.-

SPECIFICATION forming. part of Letters Patent No. 741,657, dated October20, 1903. Application filed April 6, 1903. VSerial No. 151,375. (Nomodel.)

To @ZZ whom. it may concern:

Be it known that I, MAUEOE GRAHAM, a subject of the King of GreatBritain and Ireland, residing atLeeds, in the county of York, England,have inventeda new and useful Improvement in Hot-Coke Conveyors, ofwhich the following is a specification. i

This invention relates to hot-coke conveyers for use mainly in conveyinghot coke direct from the retorts in gasworks, and is a furtherimprovement on the apparatus shown and described in the specification ofmy prior application, Serial Nori-1:1575, iled February 2, 1903.

The main object of my invention is to provide in these and other typesof conveyer an improved means Wherebythe conveyer-trough may be keptclear of the water and sediment which tends to accumulate therein byreason of the quenching and subsequent draining of the coke duringtransit. The method of driving the conveyer within the trough is alsoirnproved and simplified.

My said invention is illustrated in the accompanying drawings, in which-Figure lis a front elevation of part of a coke-conveying plant havingcertain of my improvements applied. Fig. 2 is an end elevation of Fig. 1in section on a somewhat-enlarged scale. Fig. 3 is a front elevation ofpart of a coke-conveying plant having my improvements applied in asomewhat-modified form, as hereinafter described. Fig. 4 is an endelevation of Fig. 3 in section. Fig. 5 is a front elevation of part of acoke-conveying plant having my improvements applied in a furthermodified form, vas hereinafter described.

Similar letters referto similar parts throughout the several views.

-According to my present invention the lower or return part of theendless traveling conveyer a, Figs. l and2, is inclosed within a troughI), which is connected at convenient intervals by means of suitablepipes, channels, or passages c, with the trough d inclosing the upper-or forward part of the conveyer.. The endless conveyer o is providedboth on its outer and inner surfaces with a series of hinged push-platesc. The

said push-plates on the lower side of the conveyer a (both forward andreturn) remain the surface of the conveyer.

suspended in a vertical position and are prevented from turning backupon their hinges by means of suitable projecting shoulders or stops,while the push-plates on the upper side of the conveyer close up and lieflat against The Whole of the Water and sediment accumulated in theupper trough d is therefore pushed along by the action of the hingedpush-plates e and is immediately discharged through the connecting pipesor channels c into the lower trough b, from which it is discharged intoa sump or collecting-tank at the extreme end of the trough b by theaction of the bottom pushplates e on the return part of the conveyer a.

In the arrangement shown in Figs. 3 and 4 the pipes or passagesc,leading from theupper trough d, are arranged in connection with aninclined bottom drain or trough b, so that push-plates e (either fixedor hinged) are required for the upper trough only. The water 'andsediment on reaching the bottom drain or trough b gravitates toward asuitably-placed sump or tank, the discharge being facilitated, ifdesired, by means of an occasional or constant Hush of Water along theinclined drain'or trough b, or, if desired, each of the outlets orpassages c may discharge into a separate sump or tank, from which seriesof sumps or tanks the accu mulated` water and sediment may be removed byany convenient means. 4

In the arrangement shown in Fig. 5 the upper trough cl is inclinedeither in sections, as shown, or in one continuous incline, so as toenable the Water and sediment to gravitate toward the outlets orpassages c without the use Y of push-plates. The Water and sediment isthen discharged by means of the inclined drain or troughb, as abovedescribed, or direct-into a series of sumps or collecting-tanks.

As the upper trough d is kept clear of water, the driving-wheel@l of theconveyer need not necessarily (as has heretofore been the case) bemount-ed above the level of the body of the trough d, as shown in Fig.l. `On the contrary, the driving end of the conveyer is preferablyarrangedin line with the` body of the trough d, as shown in Figs. 3 and5, or on a downward incline, as shown in dotted lines 'in Fig. 3.

IDO

To facilitate the driving of the endless conveyer a, collars f, Figs'. land 2, are provided at each joint, preferably at each end of thehinge-pin and Within the supporting runners or Wheels g, these collars fbeing adapted to t Within corresponding recesses h in the periphery ofthe sprocket-wheels t' at each end of the apparatus.

Each section or link of the endless con veyer a, whether perforated orotherwise, is provided with raised flanges 7c along the sides for thepurpose of preventing the coke from falling onto the Wheels or runners gand the collars f. One or more raised transverse ribs may also beprovided, if desired, these serving as a means of strengthening theconveyer and also as a means of retaining the coke upon the conveyerwhen Working on an incline.

lVhat I claim as my invention, and desire to secure by Letters Patent,is-

l. In apparatus for conveying and quench-` ing incandescent hot coke,the combination, with an endless traveling conveyer a Working within anupper trough (l, of a lower trough b inclosing the return part of theconveyer, a series of pipes or passages c connecting the said troughs Z)and (Z, and a series of hinged push-plates e attached on both sides ofthe said conveyer d, substantially as set forth, for the purposespecified.

2. In apparatus for conveying and quenching incandescent hot coke, thecombination, with an endless traveling conveyer ct Working Within anupper trough d, of an inclined bottom drain or trough ZJ, a series ofpipes or passages c connecting the said troughs Z) and d, and a seriesof push-plates e attached on the inner side ofthe said con veyer a,substantially as set forth, for the purpose speciied.

3. In apparatus for con veying and quenching incandescent hot coke, thecombination, with an endless traveling conveyer a, of an inclined uppertrough d, an inclined bottom drain or trough b, and a series of pipes orpassages c connecting the said troughs b and d, substantially as setforth, for the purpose specified.

The combination, With an upper conveyer-trough, and a lowerconveyer-trough; of drain-passages connecting the middle parts of thesaid troughs, and an endless traveling con veyer working in the saidtroughs.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing Witnesses.

MAURICE GRAHAM.
